To all whom it may concern."

Be it knowirtlnl-t l, ls'rnrerc ll. Gun-ms, residing at Buffalo, in the county of Erie and State ol' New- York, have invented certain new and useful l lnprovenwnls in Braking Appnmtus, olwh ieh the following is a lull, clean, and exact description, such as will enable others skilled in the nrtto which it appertuins to inn-lie and use This invention relates to braking apparatus? One ol' the objects thereof is to provide nl'orni oi ln-nkiiig uppitmtns susceptible of the hardest use without injury to the parts. f

Another object is to provide apparatus of the above sbly applied wheel.

Another obj cct is to provide a can wheel of strong and durableconstruction in which the butking surface is isolated ironi'the wheel tread.

Other objects will be in part obvious'nnd in part without contact with the trend of the The invention accordingly consists in the lectures of ment of parts which will be exenlplilied in'the construction hereinafter set forth, and the scope of the up In the accompanying drawing, wherein is shown one or more of various possible embodinients of my invention,'Figure 1 is an elevation thereof, certain parts being broken away upon line yy oi Fig ZJn-Mier to show the construction more clenrly.- Fig. 2 is a sectional view taken substantially along the line xa: of Fig! 1.
